Post-radiation lichen planus: a case report and review of the literature.

BACKGROUND: Lichen planus is a T-cell mediated inflammatory disorder of the skin and mucus membranes and is a rare complication of external beam radiation. CASE PRESENTATION: 64 year old White male who presented to dermatology with a lesion at the lateral aspect of the right thigh. The lesion was first noted 40 years prior and had grown from 1.5 cm to 6.5 cm in the ensuing years. On examination the lesion was raised, hypopigmented, with pearly borders and central ulceration. Wide excision with lymph node dissection demonstrated invasive squamous cell carcinoma, basaloid type, with negative margins. Patient had radiation therapy of the right inguinal nodes. Patient subsequently noted a "blister" on the right upper thigh, which progressed over time to flat, polygonal, intensely pruritic lesions that covered the right lateral thigh from just distal to the hip to the distal third of the femur (Figs. 1, 2). Skin biopsy was positive for lichen planus. He was started on topical triamcinolone with salutary effects on appearance and pruritus. Fig. 1 Lichen planus, right thigh Fig. 2 Closeup, lichen planus, right thigh, demonstrating polygonal papules CONCLUSION: Once more biopsy-proven cases of post-radiation lichen planus are reported, hopefully the exact mechanism can be elucidated. This may identify risk factors and aid in treatment, with the goal of limiting radiation toxicity and palliation of symptoms that may affect the quality of daily life.

Ethics Roundtable: Advance Directives, Autonomy, and Gastrostomy Placement.

CL is a 94-year-old male who is brought to the Emergency Department from an assisted living facility due to a new onset of weakness and altered mental status. He was in his usual state of moderately compensated health, requiring assistance for most activities of daily living due to medical frailty and a previous right brain CVA with residual mild left sided weakness. On the day of admission, the staff found him lethargic and disoriented. The family requested a surgical consult for percutaneous, endoscopic, gastrostomy (PEG) tube placement. A review of the patient's records showed that the patient had refused a PEG tube during his last two hospitalizations. During the last admission, the hospitalist documented that the patient repeatedly refused nutritional support stating "if it's my time, I've lived a full life. I'm ready to die and join my wife." There was no advance care plan ("living will"), but CL did sign a "Selection of Surrogate Decision-maker" form previously, assigning his nephew as primary surrogate. Under pressure from multiple family members, including the designated surrogate, the attending requested a surgical consultation. The surgical team determined that the patient did not have capacity and scheduled CL for PEG tube placement. The care team had concerns regarding the conflict between the patient's previously (and consistently) stated desires and the family's wishes; an ethics consult was requested.

Aromatase inhibitor-associated musculoskeletal pain: An overview of pathophysiology and treatment modalities.

Since their introduction into clinical use in the 1970s, aromatase inhibitors have been a cornerstone of therapy for estrogen-receptor positive breast cancer in postmenopausal women. Unfortunately, this therapy leads to estrogen depletion in the body, which can lead to unpleasant side effects such as menopausal symptoms like hot flashes, insomnia, slightly increased risk of ischemic heart disease, accelerated bone loss leading to higher osteoporosis risk, and most significantly, arthralgias. The joint pain induced by aromatase inhibitor therapy is frequently cited as the leading cause of premature discontinuation; approximately 50% of patients will report new onset or worsening joint pain 1 year after therapy initiation, approximately 30% of patients discontinue therapy after 1 year, and only 50%-68% of patients remain fully compliant with therapy after 3 years. This article will describe risk factors for aromatase inhibitor-associated musculoskeletal syndrome, including genetic predispositions correlated with an increased risk of this syndrome, explain the currently understood pathophysiology, and give an overview of effective treatment options in managing this syndrome.

Pharmacology update: pamidronate for hypertrophic pulmonary osteoarthropathy in palliative care.

Hypertrophic pulmonary osteoarthropathy (HPOA) is a rare syndrome that causes clubbed fingers, periostitis, and synovial effusions. It can adversely impact a patient's quality of life. It occurs secondary to pulmonary disease - most commonly pulmonary malignancy. The most effective treatment for HPOA is to treat the underlying disease, usually through surgical resection, chemotherapy, or radiation. However, symptomatic treatments rather than definitive treatments (surgical, chemotherapy, or radiation) are more appropriate for the palliative care patient. Pamidronate is a promising medication for the treatment of HPOA for its safety and rapid onset of action. Further research is indicated to determine whether pamidronate is consistently effective.

Hypertrophic pulmonary osteoarthropathy (HPOA) is a rare syndrome that causes pain in the long bones and typical changes in the fingers, called 'clubbing'. It can adversely impact a patient's quality of life and occur secondary to lung disease ­ most commonly pulmonary cancers. The most effective treatment for HPOA is to treat the underlying disease, usually through surgical removal, chemotherapy, or radiation. However, treating the symptoms is often appropriate for the palliative care patient. Pamidronate is a promising medication for the treatment of HPOA for its safety and rapid onset of action. Further research is indicated to determine whether pamidronate is consistently effective.

Posterior Reversible Encephalopathy Syndrome (PRES) in Palliative Medicine: Case Report and Discussion.

Posterior reversible encephalopathy syndrome (PRES) is associated with seizures, visual disturbances, headache, and altered mental status. Given its presentation, the diagnosis can be mistaken for other severe conditions. Palliative medicine consultants should be aware of PRES and be prepared to counsel families on the treatment and prognosis of this syndrome.

Case Report: Syndrome of Remitting Seronegative Symmetrical Synovitis with Pitting Edema-A Rare but Treatable Condition in Palliative Medicine.

The syndrome of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare diagnosis that is often missed due to lack of both definitive diagnostic criteria and awareness of the disease. This case report describes a patient with chronic lymphocytic leukemia whose diagnosis of RS3PE was possibly delayed due to concomitant treatment-related arthralgias. The pathophysiology, presentation, and treatment of RS3PE are discussed. Greater awareness of malignancy-related RS3PE is crucial from a palliative care perspective as typical opioid pain management will prove ineffective and delay appropriate treatment.

A Mother in Jeopardy: The Ethics of Pregnancy and Chemotherapy.

JM is a 32-year-old primagravida with polycystic ovary disease. She had extreme difficulty conceiving and was started on clomiphene 6 months ago by her fertility specialist. After doubling the dose on the sixth cycle, she successfully became pregnant. On her second prenatal visit at 12 weeks gestation, an ovarian cyst was detected. Ultrasound showed a complex ovarian mass with nodules on the bowel and abdominal wall. There was mild-to-moderate peritoneal fluid. Cytology showed adenocarcinoma of ovarian origin. Further workup demonstrated advanced stage III epithelial ovarian cancer. JM was referred to GYN-oncology who felt pregnancy-sparing debulking was not an option. The oncologist recommended termination of pregnancy due to the risks of delaying chemotherapy. JM refused, citing her fertility difficulties in the past and her desire to carry the pregnancy to term "even if it kills me." She tells the oncologist she cannot bear the thought of terminating her pregnancy under any circumstances. The oncologist wants to comply with her wishes but feels the patient is making a choice that would result in harm to herself. The oncology team requests an ethics consult.

Preliminary Validation for the "BJR method"-A Possible New Mathematical Approach to Methadone Conversion.

Methadone has been effectively utilized in the palliative care setting as a second-line agent for pain management in cancer patients with refractory pain, or in those who cannot tolerate other opioid medications. The lack of reliable dosing ratios, substantial interindividual variability in methadone pharmacodynamics, the potential for extensive drug interactions, and the high potency of methadone compared with other opioids all pose significant barriers to the use of this drug in routine practice. This article describes a novel approach to methadone conversion, with case studies providing preliminary validation.

Sildenafil for Pulmonary Arterial Hypertension.

Pulmonary hypertension is a life-threatening illness with debilitating physical and emotional consequences. The progression of this devastating disease is characterized by a continuous increase in pulmonary vascular resistance, which results in elevated pulmonary artery pressure and leads to right heart failure. Treatment is focused on targeting the underlying complex etiology via the endothelin, prostacyclin, and nitric oxide (NO) pathways. Emergence of new treatments over the past 2 decades has led to improvement in the functional status and time to clinical worsening. Even with recent advances, outcomes remain suboptimal. Phosphodiesterase-5 (PDE-5) inhibitors, such as sildenafil, were approved for treatment of pulmonary arterial hypertension (PAH) by the Food and Drug Administration (FDA) in 2005, which holds promise in improving quality of life and therefore making this class of medications effective palliative therapy agents. In this review, we summarize the emergence of sildenafil as a treatment for PAH and its role as palliative therapy.

Pharmacology Update: Low-Dose Naltrexone as a Possible Nonopioid Modality for Some Chronic, Nonmalignant Pain Syndromes.

Pain can have a devastating effect on the quality of life of patients in palliative medicine. Thus far, majority of research has been centered on opioid-based pain management, with a limited empirical evidence for the use of nonopioid medications in palliative care. However, opioid and nonopioid medications such as nonsteroidal anti-inflammatory drugs have their limitations in the clinical use due to risk of adverse effects, therefore, there is a need for more research to be directed to finding an alternative approach to pain management in comfort care setting. The purpose of this article is to discuss a potential new drug that would adequately alleviate pain and enhance quality of life without significant risks of adverse effects that would limit its use. Naltrexone is a reversible competitive antagonist at µ-opioid and κ-opioid receptors, which when used at standard doses of 50 to 150 mg was initially intended for use in opioid and alcohol use disorders. However, it was discovered that its use in low doses follows alternate pharmacodynamic pathways with various effects. When used in doses of 1 to 5 mg it acts as a glial modulator with a neuroprotective effect via inhibition of microglial activation. It binds to Toll-like receptor 4 and acts as an antagonist, therefore inhibiting the downstream cellular signaling pathways that ultimately lead to pro-inflammatory cytokines, therefore reducing inflammatory response. Its other mode of action involves transient opioid receptor blockade ensuing from low-dose use which upregulates opioid signaling resulting in increased levels of endogenous opioid production, known as opioid rebound effect. Low dose naltrexone has gained popularity as an off-label treatment of several autoimmune diseases including multiple sclerosis and inflammatory bowel disease, as well as chronic pain disorders including fibromyalgia, complex regional pain syndrome, and diabetic neuropathy. Low-dose naltrexone (LDN) may also have utility in improving mood disorders and the potential to enhance the quality of life. This article will therefore propose the potential off-label use of LDN in management of nonmalignant pain in the palliative medicine setting.

Death or Damnation: Surrogacy and Religious Beliefs.

MC is a 42-year-old female who was in a motor vehicle accident and suffered multiple contusions as well as a fracture of the left femur, pelvic ramus, and left orbit. Due to contusion of the brain, MC has been comatose for over a week and is on mechanical ventilation to protect her airway. There is no written declaration of surrogacy. During the admission, surgery to repair the left femoral fracture was performed and was complicated by severe blood loss. Currently, MC's hematocrit is 24% with a hemoglobin of 7.4. The trauma team asserts that a blood transfusion would be in MC's best interests. Since MC lacks capacity for decision making, she cannot consent to blood transfusion. Her parents are Jehovah's Witnesses and refuse to approve blood transfusion, stating that it is against their faith. MC's brother, however, states that MC is not a practicing Jehovah's Witness and wants the medical team to provide the blood transfusion. The parents insist that decision making is their right; MC's brother feels he should be making decisions. The trauma teams calls for an emergency consultation with the hospital ethics committee.

Prognostication in Anoxic Brain Injury.

Cardiac arrest is a common cause of coma with frequent poor outcomes. Palliative medicine teams are often called upon to discuss the scope of treatment and future care in cases of anoxic brain injury. Understanding prognostic tools in this setting would help medical teams communicate more effectively with patients' families and caregivers and may promote improved quality of life overall. This article reviews multiple tools that are useful in determining outcomes in the setting of postarrest anoxic brain injury.
